It should be noted that, the first housing member 21 and the second housing member 22 are all integrally formed by injection molding (Metal Injection Molding, MIM) with a POM lost foam or PMMA lost foam process, and a tunnel structure, i.e., the first opening 213, the first guide hole 214, the second opening 223, and the second guide hole 224, which cannot be formed by a common mold can be formed.

Referring to fig. 3, 4, 11 and 12, when a user wants to use the electronic device 100 and needs to separate and unfold the first body 20 and the second body 30, the second body 30 and the second housing member 22 drive the shaft sleeve 12 to rotate relative to the shaft member 11, so that the shaft unit 1 can rotate between a first position and a second position, and in the first position, the stop block 121 of the shaft sleeve 12 abuts against the left end of the wing 113 in the drawing, and at this time, the first body 20 and the second body 30 are in a folded state where they abut against each other. In the process of rotating the rotating shaft unit 1 from the first position to the second position, the stop block 121 of the shaft sleeve 12 rotates clockwise in the drawing and finally abuts against the right end of the wing 113 in the drawing, and at this time, the first body 20 and the second body 30 are unfolded to form an unfolded state with an included angle therebetween.

In summary, the threading hinge 10 of the present utility model can pass through the wire W by the arrangement of the through hole 115 of the rotating shaft unit 1 and the first housing member 21 and the second housing member 22, and the first body 20 and the second body 30 do not need to leave extra space for arranging the wire W, because the wire W can directly pass through the threading hinge 10 of the present utility model, no extra housing member is required to protect and cover the space through which the wire W passes, thereby improving the space utilization, being beneficial to the slim design of the electronic device 100, and really achieving the purpose of the present utility model.

The foregoing is merely illustrative of the present utility model and is not intended to limit the scope of the utility model, which is defined by the appended claims and their equivalents.
